Auto-translated
I personally use Hryak; I tried Windows 7, but I didn't like it, and the game runs with some lag on it.

The initial Windows version in stores is always pirated.
Or, to automate this, open the game shortcut properties, in the Target field, add the following at the beginning:
cmd.exe /C start "Heroes4" /affinity 1 (SPACE) "C:/Heroes etc. (i.e., after the space, enter your game directory)
I also recommend a setting to eliminate all animation slowdowns:
Control Panel - NVIDIA - Adjust image scaling - Disable scaling and choose GPU instead of Display.
I can't find NVIDIA in the Control Panel.
